I just ordered a Asus P5E WS PRO mobo. I saw the picture of it, and i started to wonder how the hell i will be able to fit my x-fi titanium pro PCI-express sound card in it, if both the pci-ex16`s are used by 2x 4870x2 cards, im pretty sure the top card will cover over the pci-ex1 slot. Anyone know how much space there is? And is it possible to use the PCI-X? or is that something else?
